358 ME. G. LEWIS ON JAPANESE LAKQ-URIIDJE. 



nigris, brevibus, sensim amplificatis ; pedibus piceo-seneis vel partim rufis. 

 Subtus rufo-picea. Long. 71 mill. 



This very distinct species is sculptured like L. Leioisii, and pro- 

 bably belongs to the same section of the genus. At present I 

 have only two examples, and these are apparently botb females. 

 The thorax is very parallel, and the same width in front as behind ; 

 the humeral angles are scarcely prominent, and much less so than 

 in any other Japanese species. The antennae are also shorter 

 and more robust in proportion to their length : this is a well- 

 marked character. 



I obtained the specimens on 8th May, 1881, in the Grovernment 

 forests, at a considerable elevation above Hitoyoshi. This and the 

 four preceding species sit on the leaves of perennials as described. 



Lakgtjeia eucosa, u. sp. (Plate XIV. figs. 12-13.) 



Elongata, subparallela ; capite nigro ; tborace rufo, raargine anteriore in 

 medio nigricante ; elytris punctato-striatis, cyaneis ; pedibus rufis, geniculis 

 piceo-nigris; antennis articulis 1-3 rufis, 4 picea, 5-11 nigris, 7-11 evi- 

 denter transversis. Long. 5 ad 6 mill. 



This species is very near L. ruficeps (figs. 10 & 11), but the head is 

 pitchy black or black, the knee-joints are dark-coloured, and the 

 7th and 8th joints of the antennae are clearly transverse, forming 

 apparently a 4-jointed instead of a 3-jointed club. In a long series 

 the larger size is very perceptible. Sometimes examples are red 

 beneath, sometimes pitchy red, and in others the dark anterior 

 margin o£ the thorax extends and forms a discoid spot. 



I took this species at Nagasaki, Kawasaki, Fukui, and Kashi- 

 wagi, and it is by no means rare. 



Lcmffuriaprcstermissa, J anson, is. a very distinct species, and 

 very local. I obtained only two in 1881, from the same glen, 

 behind the temple on Maiyasan, from where the type example 

 came. These measure fully 5 mill. 



Mr. Crotch formerly considered that specimens I have from 

 China, resembling atriceps and rujiceps, were really these species, 

 but they are distinct. If I remember right, his examination of 

 them was only casual. 



"With reference to the sexual characters mentioned in the pre- 

 ceding descriptions and notes, I may remark that if a male of the 

 ingens group is placed over a female as though in the act of attempt- 

 ing coition, it will be seen that the deuticulations and rough- 

 nesses on the undersides of the femora (fig. 8) scratch the surface
